SPENCER H. BROXVN, OF NEV YORK, N. Y.

INHALER AND RESPIIRATOR.

QPECIPICATION forming part of Letters Patent No. 349,687, dated September 28, 1886. Application filed December-5, 1885. Serial No. 184,855. (No model.)

To all whom it may concern:

Be it known that I, SPENCER H. BROWN, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Surgical Instruments, which I have styled an Inhaler and Exhaler, andIdo declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object of this invention is to aid nature, during the actof expiration, to expel the effetc matter from the nose, throat, and lungs.

The invention consists in the improved inhaler, in combination with an exhaler, constructed and operated substantially as will be hereinafter set forth and embodiedinthe claim.

Referring to the accompanying drawings, in which similar letters of reference indicate like parts in each of the figures, Figure 1 is a front sectional elevation of the inhaler and exhaler. Fig. 2 is a plan view of the end which is inserted into the nostrils, and is about the natural size.

In said drawings, (6 a are representations of the nostril projections, constructed of glass or other suitable material, and in shape an oval oblong.

bis a representation of the inai n exhaust-tube, also constructed of glass or other suitable material, in shape cylindrical or otherwise, and is a continuation of the nasal projections.

0 represents a joint, at which is fitted an ordinary rubber exhaust-bulb, d, or other suitable mechanical device, for the purpose of expelling the effete matter thrown off from the nose, throat, or lungs. Said joint is preferably constructed of hard or vulcanized rubber, though metal may be used. c is a representation of the valve in said exhaustbulb, which is provided with another at the opposite end thereof, working in the same direction. v p

f is a representation of the inhaling-tube, through which the remedial agencies contained in the receptacleg are inhaled or brought into contact with the diseased organs. This tube connects with the main tube b by fusion or otherwise at h, and is also provided with a joint of hard rubber or other suitable matev rial, as shown at i, the object of the joints 0 and t being to enable theinstrument to be packed in a much smaller space and to prevent breakage. The tube f is also provided with a valve, 7', a thin wafer of rubber or other suitable substance,to prevent the escape of the effete matter aforesaid from passing into themedicinal contents of the receptacle and also to prevent the contents from passing into the exhaust-tube when filled with effete mat ter, which is accomplished by having said valves open and close at opposite and alternate intervals--that is to say, valve 0 opens during the act of expiration, and the valvej remaining closed, and vice versa.

Z represents a tube for the admission of air into the receptacle in order that a perfect suction may be produced by the act of inspiration, in combination with the pressure of the outer air through said tube.

'Having thus described my invention, what I claim as new, and wish to secure by Letters Patent, is-

The combination,with the receptacle ofa jointed tube, ff, having a valve at its joint, an exhaust-tube, I), having tubular extensions a (a, exhaust-bulb d, for assisting the expulsion of exhaust air from said tube and the nostrils, and the valves in said bulb, substantially as and for the purpose set forth.
